Two of my three o/u shotguns have two triggers. I learn to shoot using two triggers and find it quicker to select the barrel/choke I need when bird hunting that to hit the selector button on my SKB when needing the tighter choke.
My guess is that the guys were just joshing with you.

I have heard of double single triggers on some really high end doubles, combining the best of double triggers and single trigger designs.
The front trigger fires the bottom or right barrel on the first pull and the other barrel on the second pull.
The rear trigger fires the top or left barrel on the first pull and the other barrel on the second pull.

The Browning Superposed (the "Twin-Single"variant) and the Mauser Model 620 are two shotguns that offered this feature on some of their guns. Imo, this double trigger set-up, at least theoretically, is by far the best approach to "barrel selection" but over time I have read that the mechanism was overly complicated, expensive to make and failure prone.

hmmm

Seems to me that I read one of Michael McIntosh's books about shotgunning in which he discusses the fact that single trigger guns have a disconnect that operates during recoil and which isolates the trigger from the sear because under recoil the trigger finger involuntarily pulls the trigger a second time.
Does that idea sound familiar to anyone else?
If I am remembering that correctly, then putting fingers on both triggers of a double trigger gun seems unwise at best.

One of the earliest solutions to the problem of single trigger guns bump firing the second barrel due to recoil pulling the gun away from the trigger finger and then bouncing back was something called the "three pull trigger". If you dry fire the gun, the first pull releases the first hammer, the second pull switches the trigger to the second sear, and the third pull released the second hammer.
During actual shooting, the trigger switches to the other sear from the gun rebounding off your shoulder after the first shot causing you to pull the trigger twice and it appears like it only takes two pulls of the trigger.
I learned about this from a book written by W.W. Greener.

My Ruger O/U has an inertia weight that blocks the trigger while the gun is under recoil to prevent a bump fire double discharge. It has a mechanical trigger, you can dry fire both barrels withoug having to bump the stock to simulate recoil to get it to switch barrels.

This is probably the first time in my life (and I'm older than seventy) that I've ever heard of using two fingers to fire a shotgun that has two triggers. A ridiculous idea imo.
a perfectly accepted technique to get more lead in the air for hunting

no but seriously I have heard oldtimers say this

And I think it is/was Perazzi that offered a sbs with a third trigger that fired both barrels at once, the barrels were even manufactured with a slight dispersion, to get as big a swarm as possible

One finger,either bbl first.

Many side by sides are fine old shotguns of considerable value.

There is a style of using them.Not slamming them open and closed ,for example.

They are generally made to be as light and slender as possible,with the exception of some waterfowl guns.There is not extra wood in them for overkill strength.
Particularly with sidelocks.

Subjecting them to the recoil of doubling is a bad idea.

One of the problems with shooting both barrels at once is that it is virtually impossible to shoot both barrels exactly at the same time, one will always shoot a fraction of a second before the other. Because of the recoil of the first barrel resulting in barrel jump, the second barrel will always shoot over the target.

Try it on a big patterning board if you don't believe me.

Also, the bore lines of double barrels converge to compensate for barrel jump during the shot's barrel travel. The top barrel of an O/U jumps more than the bottom barrel so it has to be aimed lower to hit the target. The left barrel of a SXS jumps up and to the left while the right barrel jumps up and to the right.

I've always figured having both barrels going off exactly together would put a lot of stress on the weild.
But I've spoken with my SG guru (my grandfather) and he says he used to shoot with one fella pretty regularly who used a two finger method. And was left handed to boot. Says he shot well enough to hang with the big boys. So I suppose there are folks out there who do this.
